These words do not have one shared technical scale. The definitions below say what each word describes and what it does not tell you, so you can ask the seller the right question instead of comparing labels.
Recline position that spreads body weight; brands sell it as 2-step or 3-step positions.
The number of steps and the recline angle are brand statements with no shared standard; compare each brand's own wording, do not treat '3-stage' as an equal performance grade.

A long L-shaped guide rail whose curve follows the body, carrying rollers from neck to thighs.
S/L/SL describe rail shape; the massage coverage each brand claims for the same word differs. Osaki writes 'SL-style Track'.

Brand wording for a roller mechanism claimed to add speed/depth control on top of 3D.
No industry definition was found on the checked pages; the same model can be titled 4D on Amazon and described elsewhere as a 3D mechanism. Record each brand's own wording only, never a cross-brand 4D ranking.

Transparency
The steps below describe what was actually done for this site, not a laboratory or hands-on process.
Every card, table, filter and check on this site is rendered from a single model library. No page keeps its own copy of a specification.
A value is shown with the type of source it came from (Amazon seller listing or manufacturer's own page) and the date that page was checked. Values that are not stated are shown as not published, never guessed.
We do not test, measure or unbox chairs. We do not display star ratings, review counts, review summaries, prices or availability. Negative-review claims are left out because no review text was collected.
"4D", "SL track" and "zero gravity" are brand wordings with no shared scale. They are reported as each listing states them and are never ranked against each other.
We do not display prices or availability. Prices change; check the current price on Amazon before you buy. No independent third-party measurements are shown on this site. Every number is either the seller's listing statement or the manufacturer's own statement.
